On the market today, there are many types of gasoline and diesel motorcycles, first of all, we will learn about the parts that make up the outstanding features of gasoline and diesel motorcycles. 

 The table compares the characteristics of diesel and gasoline motorcycle parts: 


Diesel motorcycles (diesel)

Gasoline motorbikes

Piston weight

1.8 kg


Compression ratio

~14:1 – 23:1

~8:1 – 12:1

Combustion chamber pressure

~ 35 - 40kg/cm2.

~ 7 - 12kg/cm2.

Spark plug

Spark plugs

Spark plugs

From the listed characteristics, we will dive into the details that make the difference between the following 2 petrol and diesel motorcycles:

1. Engine power

When it comes to engine power, there are two big issues: power and traction.

  • Wattage:

Considering the same cylinder capacity, the gasoline engine (diesel) will have a larger capacity. The reason is because the structure of the diesel piston with a large rpm and faster rebound will create a large capacity. 

However, today with the development of new technology, many companies have launched diesel engine products with small capacity but very large capacity, for example: the 2.2l diesel version SantaFe model 200 horsepower capacity, while the 2.4-liter gasoline version has a capacity of 190 horsepower. 

Hyundai SantaFe Diesel version 2.2l, capacity 200 horsepower.

Hyundai SanatFe petrol engine version 2.4l engine, capacity of 190 horsepower.

  • Stretching:

 Diesel engines have a lot more traction than gasoline engines. Because each movement of the piston will create a very large force, the ability to generate heat from that will also be higher than that of the gasoline piston. For example, SantaFe's diesel engine has a pulling power of more than 400N/m, while SantaFe's gasoline engine has a pulling power of just over 200N/m.

The advantage of the diesel engine is that the traction power, also known as the large torque, will work with heavy loads on mountainous terrain, or moving at very slow speeds, the diesel engine will promote its advantages with high power. Very good towing when moving on mountain passes. 

Therefore, most commercial vehicles, trucks, passenger cars, and specialized vehicles choose diesel engines to both have great traction capacity and optimize fuel consumption.

2. Fuel consumption

If the gasoline engine has to work at higher rpm, more gasoline is injected while the diesel engine works at lower rpm, less fuel is injected. And the price of diesel engine is also much cheaper than the price of gasoline engine.

With current prices, an average gasoline engine traveling 100km will cost 200.000 VND, equivalent to 2000 VND/km and with diesel engines, the consumption cost will be reduced by almost half, equivalent to 1 VND/km.

3. Sound insulation ability.

Diesel engines make more noise than gasoline engines. Due to the large compression ratio, the compression pressure in the combustion chamber is very high, so it will create a loud noise. While the gasoline engine makes very little noise when starting the engine, even you have to pay attention to detect the engine noise. 

The quietness and soundproofing ability when traveling on the road depends a lot on other factors, if traveling from 0km to 60km/h, diesel cars are usually noisier than petrol engines from 2-5 dB. Moving at a speed of 70-100km / h, the soundproofing ability of a diesel engine will still be noisier than a gasoline engine car.

4. Engine durability

The durability of the engine with the same manufacturer, the same technology, and used in harsh conditions such as heavy loads, running more than 1000km/day, diesel engine is the number 1 choice. Durability of a vehicle based on the owner's maintenance and repair conditions.

5. Maintenance cost

The two most mentioned factors are fuel and ignition.

  • Fuel:

Because diesel engines often work at higher pressures, resulting in more fuel injectors working, the cost of fuel injectors will be more expensive than gasoline engines. In the process of use, pumping gasoline at reputable gas stations to minimize unqualified fuel, many impurities will greatly affect the internal engine. 

Clean the fuel injectors regularly to keep the engine running smoother with higher efficiency. With the injector of a gasoline engine, the fuel injector will be smaller, so the cost will also be cheaper.

  • Ignition:

Gasoline engines need spark plugs and high-pressure systems to power the spark plugs and other factors that make the maintenance costs of gasoline engines much higher.

In general, gasoline engine is complicated in electrical system, diesel engine is more complicated in fuel injection system, If the vehicle is used in normal conditions, quality fuel, maintenance and repair If fully repaired, a diesel engine vehicle will have lower maintenance and repair costs than a gasoline engine vehicle.
